MlTER-BOX.

SPECIFICATION forming part of Letters Patent N0. 760,982, dated- May 24, 1904.

Application filed September 17, 1903. Serial No. 173,577. (No model.)

T at whOm it may concern.-

Be it known that I, WILLIAM H. GORDON, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Miter-Box, of which the following is a specification.

My present invention relates to improvements in that type of miter-boxes generally disclosed in my Patent No. 621,524, and it seeks to produce an improved construction of miter-boxes especially designed to provide for a special adjustment of the saw with respect to the material worked on and a follower to steady back of saw when large materials are to be worked on and for providing guides of any height to suit the work to be done Whereby to produce a miter-box of unlimited capacity for any kind of carpentering and especially adapted for quickly and accurately adjusting the saw-guides to any desired single pitch or two pitches at one time.

With the above object in view and others to be hereinafter explained my invention comprehends generally a suitable bed or table having means for detachabl y supporting workrests, a saw-guide disposed intermediate the work-rests and adjustably connected to the bed to swing in either direction in the longitudinal plane of the bed and movable axially with respect to the pivotal connections which sustain the said guide for its longitudinal or sweep movements.

In its more complete nature my invention includes a bed-plate, a socket pivotally mounted thereon to rock in the longitudinal plane thereof and having a graduated segment with which a fixedly-held pointer cooperates, a second socket or casting in which is detachably held the. saw-guides and which has a shank to engage the rocking socket and be rotatably swung therein and which is also provided with suitable graduations for cooperating with a pointer fixedly held on the rocking socket whereby the guides can be accurately set to the positions desired.

In its more subordinate features my invention embodies certain details of construction and peculiar combination of parts, all of which will be fully described, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which-- Figure 1 is afront elevation of my improved miter-box, the saw-guide being shown swung to the right in dotted lines. Fig. 2 is a plan view thereof. Fig. 3 is a cross-section taken practically on the line 3 3 of Fig. 1, the saw-. guide, the follower, and one of the workclamps being also shown in their operative positions. Fig. 4 is a longitudinal section, on an enlarged scale, of a portion thereof, taken practically on the line 4 4 of Fig. 2. Fig. 5 is a plan view, on an enlarged scale, of the bed-plate shown in Figs. 1 and 2 with the rocking socket mounted thereon. Fig. 6 is a front elevation thereof. Fig. 7 is a rear elevation of a portion thereof. Fig. 8 is a full-size front view of the rocking socket hereinafter referred to. Fig. 9 is a back view thereof. Fig. 10 is an end elevation thereof. Fig. 10 is a detail view hereinafter specifically referred to. Fig. 11 is a full-size side view ofthe lower end of the saw-guide with its graduated collar. Fig. 12 is an inverted plan view thereof. Fig. 13 is a detail view of the rocking socket, together with the saw-guide. Fig. 14 is a longitudinal section of a one way miter-box. Fig. 15 is a detail view of a slightly-modified form of detent or lock devices for looking a saw-guide to its axial adjustment as used with the one-way miter-box. Fig. 16 is aperspective View, on a reduced scale, of the one-way miter-box. Fig. 17 is a perspective view, on a reduced scale, of the preferred form of my miter-box, illustrating the manner of adjusting it for cutting jack-rafters or rake moldings on one or two pitches at the same time.

Referring now to the accompanying drawings, it will be seen that in my present construction of miter-boxes the operating parts are supported upon and attached to a wooden bed 1, mounted on cross-cleats 2, to the under side of which is detachably mounted the metal bed-plate 3, (shown in detail in Figs. 5 and 6, which illustrate the preferred form,) and the said bed-plate consists of a rectangular flat body provided at the opposite ends with sockets 3 3, the upper ends of which are designed to enter apertures in the wooden bedplate 1, as shown, and the said sockets are conical and of slightly less diameter than the conical tenons 1 of the wooden work-rests 4:, whereby to provide for a tight fit of the said rests therein. The plate 3 is secured to the bed 1 by bolts 5 5 and is preferably braced ently again referred to, the purpose of which will presently appear. The central plate also has an elongated opening 1, which cooperates with the opening 1 in the wooden bedplate for a purpose presently explained.

5 designates what is hereinafter termed the rocker-socket, which is in the nature of a cup-shaped body, and the said socket 5 is mounted between the side wings 3 upon studscrews 6 6, which engage the diametrical opposite conical bearings 5 in the socket 5, and which forms the pivots upon which the said socket is held to swing or rock in the longitudinal plane of the bed-plate, and the said sockets 5 are also formed at their opposite or pivot sides with pendent integral sector-plates 5, the periphery edges of which have graduations to designate square octagon and square miter cuts and which radiate from the pivots of the sockets. The said plates 5 are also provided with a set of depressions 5, arranged concentric with the pivots which engage the screw 7 that holds the sockets 5 to the exact angle for the plumb octagon and square miter cuts. On the rear face the rocker-socket has a threaded aperture 5*, with which engages the clamp-screw 5 which passes through a slot 3 in the rear wing 3, and the said screw 5 serves to clamp the socket 5 to any position it may be set-either the plumb octagon or square or intermediate position. 1

The saw-carrier consists of a metal bifurcated socket, the lower end of which has a series of graduations 10 for designating square octagon and square miter cuts, also different pitches of roofs and which aline like graduations 11 of the collar 11, screwed upon or otherwise fixedly held to the under side of the socket 10. The collar 11 has a series of radially-disposed l\ shaped grooves in its under face which are relatively spaced in harmony with the graduations 10 11 and which are arranged to engage with the l\- shaped radial tooth o of the socket 5, such.

arrangement of the grooves and tooth being provided to permlt of setting the guides at angles of different degrees in the horizontal plane. I may dispense with the collar 11 and form the I\-shaped grooves in the under face of the carrier 10, if desired.

The saw-carrying socket 10 has a pendent spindle 10, adapted to be mounted in the socket 5, whereby-the said carrier 10 is axially adjustable with respect to the. socket 5 and adjustable in the longitudinal plane of the table in opposite directions by reason of the pivoted socket 5, as before stated, and by reason of such correlation of parts it is manifest the carrier 10 can be swung either laterally at an angle or angles to cause the same to cut at the desired lateral pitch or it may be used both laterally and radially to cause the saw to cut at the desired transverse angles, as well as the longitudinal pitch, at the same time. To hold the carrier to its axial or rotary adjustment, I preferably provide a thumb-screw 1O to clamp the dependent spindle 10 to the socket 5, as clearly shown in Fig. 4:.

- In order to properly cut short work, I provide wide cleats, marked 17, (shown in dotted lines in Fig. 1,) said cleats extending to the center of work-rests, said work-rests holding cleat, which is of the same width as saw-guide and work-rests, all being cut to fit around work-rests and held in place by the pin marked 15. (See dotted lines, Figs. 1 and 2.) In the one-way miter-box I may dispense with the cleats 17 by substituting extra cleats in the bed-plate to carry work-rests, as shown in dotted lines in Fig. 14.

, In Fig. 10 I have shown a slightly-modified form of I\-shaped tooth, which consists of a longitudinal member 5, adapted to fit in the countersunk groove 50" of the rockersocket 5, and the said member 5' is held in the said groove by screws 5 as shown, whereby the same may be detached and a new one substituted whenever it may be found desirable to do so.

In Fig. 14 I have shown a slightly-modified form of my invention, in which the'bed-plate 3 is formed with a central pendent socket 30, into which the pendent portion 10" of the sawguide-carrier socket 10 is adapted to fit, and the said bed-plate is provided with a /\-shaped tooth 5' to cooperate with the l\ shaped grooves in the under side of the collar 11, and the said saw-guide socket 10 is held to its adjusted positions by a thumb screw 15, as shown.

In Fig. 15 I have shown a saw-guide socket 10, graduated above the bed 1, and it has a series of properly-spaced depressions to cooperate with the self-locking pointer 13, mounted in the guide-bearing 13", secured to the bed 1 and having a pointer 13 to cooperate with the graduations on the said saw-guide socket, as shown in Fig. 15. I also form the member 3 with a bearing 13 to receive a second locking member 13, mounted on the under sideof the bed-plate, which has azportion 13 adapted to enter depressions in the member 10, as shown in Fig. 13.

In my present invention I also utilize a follower device for the saw which serves to steady the said saw; and it consists of a pair of link bars 16, pivotally connected to and held to straddle the clamp boards orpieces 18 18, held in the saw-guides and between Which the saw is worked, the outer ends of which pivotally connect with the clamp-blocks 19, that fit over the upper edge of the saw, as clearly shown in Figs. 16 and 17 which illustrate the saw adjusted to make a jack-rafter cut for one-halfpitch roof. In the complete form of my miter-box I also use [I-shaped bars 20, which are detachably mounted on the bed 1 for holding the stock up against the work-rests.

From the foregoing it will be seen that I provide a miter-box which can be worked from both the front and the back, whereby when a miter is cut at one side of the box obliquely across the face of the bed at any angle the reverse cut can be made without changing the said position of the saw-guide and a more perfect fit can be made by simply using the other side of the box, thereby insuring a more perfeet out and a more perfect fit of the cut mem' bers than is possible in the ordinary manner of sawing miters and regardless of the condition of the saw, which if used without the box may possibly run crooked, owing to its being improperly filed.

From the foregoing, taken in connection with the accompanying drawings, it is believed that the complete construction and manner of operation, as well as the advantages of my invention, will be readily understood by those skilled in the art to which it appertains.

I desire it understood that slight changes and modifications in the detail construction and arrangement of parts may be made without departing from the scope of the appended claims.
